Answer:
2
Step-by-step explanation:
The proportionality constant k is given by y/x
y/x = cost/ channels = 84/42 = 2
The constant is $2/ channel
Answer:
y= 2 x= 1
$84 divided by two is $42, which would mean mom is paying $2 per channel.

What is the sum of the following?
88x+4y+2x+1y
Hey there!☺
[tex]\text{Answer: }\boxed{90x+5y}[/tex]
[tex]\textbf{\text{Explanation:}}[/tex]
[tex]88x+4y+2x+1y[/tex]
In our first step, we will need to identify like terms.
[tex]\textbf{88x}+4y+\textbf{2x}+1y \rightarrow \text{x variables are like terms}\\88x+\textbf{4y} + 2x + \textbf{1y} \rightarrow \text{y variables are like terms}[/tex]
Now that the like terms have been identified, we will need to add them. Adding variables are simple; you add the whole numbers while the variable says the same.
[tex]88x+2x=90x[/tex]
[tex]4y+1y=5y[/tex]
Now, we will add.
[tex]90x+5y[/tex]
The answer is 90x+5y.
Hope this helps! ☺
Tickets to the North Carolina State Fair
are $6 for adults and $2 for children under 12.
If the 1st grade at Smith Elementary School
went to the fair with 24 chaperones and the
total ticket cost came to $444, how many 1st
grade students went?
Answer:
150 1st graders
Step-by-step explanation:
do 24 times 6 because there are 24 adults and each of their tickets cost $6. you will get 144. do 444-144 to get 300 because uou want to subtract the money the adults have to pay. Since it's $2 per kid, just divide 300 by 2 to get 150. Hope this helps :)

HELPPPP!!!! (20 points) The table below shows the account balances for four different customer accounts at the City
Bank. Which account balance represents a debt that is greater than $20 and less than $30?
Account Balance (S)
S25
-S34
-$24
$17
Answer:
$25
mark as brainlist answer
The account balance that represents a debt that is greater than $20 and less than $30 is -$24.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
The account balance= $20 and less than $30
Account Balance (S)
S25,-S34,-$24,$17
Now,
Note that a negative account balance indicates a debt, and the absolute value of the account balance represents the amount of the debt. In this case, the account balance of -$24 represents a debt of $24, which is greater than $20 and less than $30.
Therefore, by algebra the answer will be -$24.

* Describe how circle, parabola, ellipse, hyperbola are formed in a conic section. (include axis, vertex, vertical angles in a figure).
Step-by-step explanation:
In mathematics, a conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though historically it was sometimes called a fourth type. The ancient Greek mathematicians studied conic sections, culminating around 200 BC with Apollonius of Perga's systematic work on their properties.
Types of conic sections:
1. Parabola
2. Circle and ellipse
3. Hyperbola
Table of conics, Cyclopaedia, 1728
The conic sections in the Euclidean plane have various distinguishing properties, many of which can be used as alternative definitions. One such property defines a non-circular conic[1] to be the set of those points whose distances to some particular point, called a focus, and some particular line, called a directrix, are in a fixed ratio, called the eccentricity. The type of conic is determined by the value of the eccentricity. In analytic geometry, a conic may be defined as a plane algebraic curve of degree 2; that is, as the set of points whose coordinates satisfy a quadratic equation in two variables. This equation may be written in matrix form, and some geometric properties can be studied as algebraic conditions.
In the Euclidean plane, the three types of conic sections appear quite different, but share many properties. By extending the Euclidean plane to include a line at infinity, obtaining a projective plane, the apparent difference vanishes: the branches of a hyperbola meet in two points at infinity, making it a single closed curve; and the two ends of a parabola meet to make it a closed curve tangent to the line at infinity. Further extension, by expanding the real coordinates to admit complex coordinates, provides the means to see this unification algebraically.

Answer:
14x + 2
Step-by-step explanation:
The perimeter of a rectangle is all the sides added. So, you would do
2x + 4 + 2x + 4 + 5x - 3 + 5x - 3
2x + 2x + 5x + 5x + 4 + 4 - 3 - 3
4x + 10x + 8 - 6

Find the LCM of the pair of numbers. 5 and 35 The LCM is I
Answer:
The LCM of the numbers 5 and 35 is 35.
Answer: The answer to this math question about finding The Lowest Common Multiple (LCM) of the given pair numbers for #5 and #35 is LCM = 35.
Step-by-step explanation: This is another same thing, according to the online calculator website called, "Calculatorsoup.com", I chose to find the list of the multiples given with the pair of the numbers, so anyways, here are the following steps in order to find The Lowest Common Multiple (LCM) with the given following pairs #15 and #8 are being shown here below:
Please find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.1. Here are the list of the multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45.
2. Here are the list of the multiples of 35: 35, 70, 105.
So, therefore, the answer to this math question about finding The Lowest Common Multiple (LCM) of the given pair numbers for #5 and #35 is LCM(5, 35) = 35. And as always to remember the legends, according to the online calculator website is called, "Calculatorsoup.com", the bold and the underline is being indicated that the first common multiple is founded, and without the given bold and the underline is being indicated that the first common multiple has not been found yet.I hoped that my given answer with my given explanation is very helpful to your own math question about finding The Lowest Common Multiple (LCM) of the given pair numbers, also using my given hint to find the first common multiple is also helpful to your own math question as well according to the online calculator website is called, "Calculatorsoup.com", that's all for today, please mark me as Brainliest, have a rest of a great day and good night! :D

Given f(x)
-4x - 10 and f(x) = 10. what is the value of x?
Answer:
x = -5
Step-by-step explanation:
f(x) = -4x - 10 and f(x) = 10
Step 1: Substitute 10 for f(x)
10 = -4x - 10
Step 2: Add 10 to both sides to get x alone
10 = -4x - 10
+10 +10
20 = -4x
Step 3: Divide both sides by -4 to get x alone
20 = -4x
-4 -4
x = -5

A family bought a total of 16 adult and child tickets to a magic show.adult tickets are 10.50 each and child tickets are 7.50 each .the family paid a total of $141
Answer:
There were 7 adults and 9 children paying tickets to the magic show
Step-by-step explanation:
System of Equations
A system of equations consists of more than one variable related to more than one equation. The question we're working on requires to know two variables: the number of children and the number of adults that paid to a magic show.
Let's call x to the number of adults and y to the number of children. The first condition states there are a total of 16 persons in the group. This can be written as:
[tex]x+y=16[/tex] [1]
We also know the adult tickets cost $10.50 each and child tickets cost $7.50 each. This means the total amount paid for the tickets is:
[tex]total\ paid = 10.50*x+7.50*y[/tex]
We are given this total, thus
[tex]10.50*x+7.50*y=141[/tex] [2]
The system formed by [1] and [2] must be solved to answer the question. Let's solve [1] for x:
[tex]x=16-y[/tex]
And substitute x in [2]:
[tex]10.50*(16-y)+7.50*y=141[/tex]
Operating:
[tex]10.50*16-10.50*y+7.50*y=141[/tex]
[tex]-10.50*y+7.50*y=141-10.50*16[/tex]
Joining like terms and operating on the right side:
[tex]-3y=-27[/tex]
Solving:
[tex]\displaystyle y=\frac{-27}{-3}[/tex]
[tex]\boxed{y=9}[/tex]
The value of x is calculated by
x=16-y=16-9
[tex]\boxed{x=7}[/tex]
This means there were 7 adults and 9 children paying tickets to the magic show
The coordinates of point A are (-3, 6) and the coordinates of point B are (3-6). Find the slope of AB
A) The slope is 2.
B) The slope is 0.
C)The slope is 1 / 2
D) The slope is -2.
Answer:
B
Step-by-step explanation:
Answer:
it should be 2, A
Step-by-step explanation:
you label (-3,6) as your x1 and y1 and label (3,-6) as your x2 and y2 you subtract y2 -y1 and get -12 and subtract x2-x1 and get -6 you divide -12 by -6 and you get 2
